- Horse soring is a painful practice used to accentuate a horse's gait to win big prizes, such as Tennessee Walking Horse competitions. This is accomplished by irritating the forelegs through the injection or application of chemical or mechanical irritants.here are two types of horse soring — chemical and mechanical. The woman in the image above is a volunteer who is trying to help a horse confiscated from a sorer by rinsing corrosive chemicals from his forelegs. You will see that the horse is also wearing stacks.

ganglion The condition can recur if the entire cyst is not removed. A ganglion is a non-cancerous cyst filled with a thick, jelly-like fluid. Ganglions can develop on or beneath the surface of the skin, most likely on the hand or wrist, although runners and skiers often develop them on the foot.

- The layer of cells at the front of the retina contains the retinal ganglion cells, whose axons pass across the surface of the retina, collect in a bundle at the optic disc, and leave the eye to form the optic nerve. Each eye contains about 125 million rods and cones but only i million ganglion cells.

preganglionic vs post ganglionic neurons In vertebrate anatomy, a ganglion is a tissue mass that contains the dendrites and cell bodies (or somas) of nerve cells, in most case ones belonging to the peripheral nervous system. Within the central nervous system such a mass is often called a nucleus. An interconnected group of ganglia is called a plexus.

Ganglion cyst Ganglion cyst. Not to be confused with Ganglion (nervous tissue structure). A ganglion cyst is a soft tissue lump that may be associated with any joint, but most often occurs on, around, or near joints and tendons of the hands or feet. These cysts are caused by leakage of fluid from the joint into the surrounding tissue.

Histology Photomicrographs drg = dorsal root ganglion. dh = dorsal horn of spinal cord gray matter. vh = ventral horn of spinal cord gray matter. In the dorsal root ganglion at 100X and 400X the sensory neuron cell bodies ncb are visible as large cells stained light and medium purple. Glial cells called satellite cells sc surround the neurons. The satellite cells in this image are the small dark purple cells.

MRI of the wrist Ganglia are the most common benign tumors of the soft tissues of the hands, found in both the volar and dorsal periarticular topographies.A ganglion is defined as a cyst in contact with a joint capsule or tendon sheath. It contains thick, gelatinous material and a thin capsule,without internal synovial lining.
